Der Vorschlag ist derzeit noch nicht vom FESCo-Ausschuss (Fedora Engineering Steering Committee), der f\u00fcr die technische Entwicklung des Fedora-Distributionspakets verantwortlich ist, genehmigt worden.    <\/p>\n<p>Als Gr\u00fcnde f\u00fcr den Wechsel werden eine aktivere Entwicklung von EROFS (die letzte Version des Tools SquashFS erschien im Fr\u00fchjahr 2023) und die vorhandenen erweiterten M\u00f6glichkeiten von EROFS angef\u00fchrt, die in Zukunft genutzt werden k\u00f6nnten. Es ist geplant, alle Builds, die ein Abbild im Nur-Lese-Modus verwenden, wie z. B. Live-Images mit KDE, Xfce, Budgie, LXQt, MiracleWM und COSMIC sowie die Editionen Fedora KDE Plasma Mobile und Fedora CoreOS Live, auf EROFS umzustellen.      <\/p>\n<p>Die Dateisysteme SquashFS und EROFS sind f\u00fcr den Betrieb im &#171;Nur-Lesen&#187;-Modus konzipiert und bieten eine kompakte Darstellung von Metadaten sowie die Speicherung von Daten in komprimierter Form. Das EROFS (Extendable Read-Only File System), das von Huawei entwickelt wurde, konzentriert sich darauf, maximale Leistung zu erzielen. In EROFS wird ein von anderen FS abweichendes Verfahren zur Datenkompression verwendet, bei dem die resultierenden komprimierten Bl\u00f6cke von fester Gr\u00f6\u00dfe genutzt werden (w\u00e4hrend bei anderen FS die Bl\u00f6cke vor der Kompression festgelegt sind und die Gr\u00f6\u00dfe nach der Kompression variiert).     <\/p>\n<p>Im Vergleich zu SquashFS hat EROFS eine geringere Kompressionsrate (Gr\u00f6\u00dfe des Abbilds 2,7 GiB in EROFS gegen\u00fcber 2,0 GiB in SquashFS bei Verwendung des Kompressionsalgorithmus XZ und 3,9 GiB gegen\u00fcber 3,1 GiB bei Verwendung von LZ4), bietet aber eine h\u00f6here Zufallszugriffs- und Daten\u00fcbertragungsrate (7,1 MiB\/s in EROFS gegen\u00fcber 5,0 MiB\/s in SquashFS f\u00fcr XZ und 30,9 MiB\/s gegen\u00fcber 26,3 MiB\/s f\u00fcr LZ4). Im Vergleich zu Ext4 ist das EROFS-Dateisystem bei zuf\u00e4lligem Zugriff auf Daten erheblich schneller \u2013 bei einem Kompressionsniveau von 4 war EROFS auf Flash-Speichern fast dreimal und auf Festplatten sechsmal schneller.<br \/>\n<br \/>Quelle: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=62566\">opennet.ru<\/a>
